Debate on the gap on the front shock mount

I have read about this gap here and other sites. Most people say this gap is normal and needed.

Well I can say I’ve worked on cars all my life. While never on a beetle, this gap bothered me since I rebuilt the front end a few years back as I’ve never seen this on any other car. Every time I hit a bump I alway felt the shock go through my spine. My logic was not when the tire moves up, but when you go over a hole in the road that pulls the tire down it seems that it would travel down until the cap stops and bangs.

So after another repair last week, I decided to try something and made rubber spacers and put them under the cap. They are 1/4” thick.

Wow - what a difference in the ride. No more banging.

Naturally after installing these I now see a company actually makes them for $55.

These are simple rubber washers. I had thought about plastic, but opted for the softer material.

So weather or not my logic holds true, my car rides much better.

The typical scenario, is the rubber strut bushings get compressed and then you have the gap; did you ever replace them before and if f you did, what brand did you replace them with?

When I rebuilt the front end a few years back, I did change the complete strut assembly. I just found the receipt, KYB brand, but the gap was there with the old and "new" struts at that time. I just read here and other sites this was "normal". It has bothered me for a few years now. This week I decided to see the effects of my homemade washer. I should have done this years ago....

Many times the replacement fully assembled strut assemblies are not the best quality; the strut bushings are notorious for compressing after a while, gaps from reduced height and it may be that the parts included in the assembly, were of lower quality. Because of this problem with the rubber strut bushing; I upgraded mine to 034 Motorsport versions, which are a bit stiffer durometer rubber than the originals and they seem to be holding up OK with no gaps.

Most Volkswagens of this era that have worn struts will have gaps; it makes sense that your spacers you installed, reduced or eliminated the gap and the clunky noise went away?

The gap on a new set of strut bushings is entirely normal. The rough ride you were feeling is likely the result of the low quality Keep Your Bilsteins (KYB) failure. I change out my strut bushings with new about two or three times over the life of a good strut such as Bilstein.

Though with a harder bushing that’s not such an issue.

Like Billy I have gone with a harder durometer rubber. The rule of thumb is that when the gap exceeds 10mm (1/2”) it’s time to think about changing the bushings.

Something like these.

Thanks jarhead. I have great respect for you and Billy with your knowledge on these cars. You have just proved my point that there is a debate over the gap, where you say it’s “normal” and Billy states low quality parts cause this and there is a fix with hd bushings. Two very knowledgeable guys in my mind.

The gap maybe be normal, but in my mind, it was the source of the horrible ride as I stated above. What I know from my experience on my car only, the washers I installed seem to make a huge difference when hitting divots in the road.
I just thought I would share my results.

Thanks again for you guys as I have learned much from your expertise.
